World Farm
The World Farm is an artificially created planet, located beyind the Galactic Rim planets. It is inhabitted, and was presumably created, by the Progenitors.
It is the only known source of Primagen, from which Terrigen crystals, Isogen orbs, Amphogen water, the Antigen Tree, and Exogen spice were created.
The only known non-Progenitors to enter the World Farm were the members of the Royal Inhuman Expidition, who located it by calculating the flght paths of the Skyspears to their point of origin.
